Abstract
Conference Title: 2013 International Conference on Current Trends in Information Technology (CTIT) Conference Start Date: 2013, Dec. 11 Conference End Date: 2013, Dec. 12 Conference Location: Dubai, United Arab Emirates Brain computer interfaces have become one of the growing areas for human computer interaction research. Various research studies were conducted to control graphical user interfaces using brain computer interface methods. Furthermore, eye tracking was another input modality that has been examined for controlling interactive systems. In this paper we investigate object selection using P300 brain signals and eye tracking across consistently design graphical user interface. We conducted several experiments on each approach on able-bodied subjects. The aim of these experiments was to evaluate and compare the accuracy and time to complete the task for both approaches. Experimental results indicated that the accuracy of eye tracking as an input modality was 92.5% on average, with 80% of participants reaching 100% accuracy. In contrast, P300 was found to produce low accuracy and efficiency results compared to eye tracking with average accuracy 32% among 20 participants. [PUBLICATION ABSTRACT]
